sclaims. (cisne-s2) This invention relates to scaffold ledger bracketsof the detachable ltype found usefulin the erection of temporaryscaffolds The invention forming the subject matter hereof constitutes animprovement upon thesubject matter of Letters Patent 2,321,916, grantedto me on June 15, 1943,`for improvements in a Scaiold ledger bracket.

In building construction and maintenance it is generally necessary toerect a temporary scaf-V folding. To -avoidmakeshift and unsafestructures it is desirable to provide a bracket means with which astrong, safe scaffold may be conveniently and quickly erected. Moreover,it is desirable that the bracket device be extremely simple to installand dismantle andjth-at it be susceptible of repeated re-use. Beyondthis, it is important that the bracket element of the scaffold should besafe to use andcapable of supporting weights, and withstanding stressesand strains, far in excess of those towhich it would normally besubjected in ordinary use.

The device forming the .subject matter of this application attains thestated objects, andothers v to become more apparent as `thisspecification proceeds, and will be found useful in this art.

In the drawing wherein a preferred form o bracket III is struck from aone-piece rectangularl blank of metal. In stamping out the bracket topand bottom nailing apertures II are punched in the plate adjacent itsrespective ends. Additionally, three nailing apertures I2 are 'struck'in the area lof the blank adjacent the upper nailing apertures I I.

Intermediate the ends of the blank forming the bracket Il) there is cut,as by stamping, an elongated slot I6 which receives a conventionalscaffold ledger board (indicated in broken lines inFigureslandZ).

It will be noted from Figure 1 that with a blank thus punched andstamped but four bends are required to produce the finished bracket. Theblank is first bent transversely and inwardly at right angles at eachend of the elongated slot I6, and then the inwardly bent portions are`bent transversely and outwardly at their mid-points to denelegs I3 andI4 and wall plates I8 and I9 respectively. When the Wall plates I8 andI9 are laid against a wall structure the device presents a crownedportion I5, slotted asiat I6, to

accommodate and support the end of a/scalfold a ledger board is insertedin' the bracket through the slot I6 of the crowned4 portion I5,abuttingthe Wall surface and resting upon the leg I4. The ledger board is thensecured to the bracket by driving a single nail in a selected one of thenail holes I2 in leg I3, depending upon the angle which the ledger boardmust assume in relation to the bracket I0. In Figure 2 there isillustrated a three-position connection of the ledger board to bracketIU indicating that the bracket is adaptable for use at a buildingcorner, as well as in those instances wherein thev ledger board will bedisposed at right angles to the w-all plates I8 and I9.' It isunnecessarythat the nail driven through aperture I2 to connect theledger board and bracket I0 be driven all the way home as it plainly ananchorage nail and may therefore have sumcient of its shank protrudingto permit quick dismantling.

When it is desired that the scaffolding be dismantled, the anchoragenail driven into theedge of the ledger board through nail hole I2 iswithdrawn and the board is removed from the bracket. Following this, legI4 of bracket I0 is tapped upwardly to move wall plates I8 and I9 withrespect to the nails driven through said plates and yto bring the nailheads into registry With the larger diameter of apertures II. Thebracket III may be liftedover the nail heads and away from thesupporting wall. Consistent with common practice, the nails may then rbedriven home t0 form a permanent part of the supportp ing wall structure.I

It will be apparent to those skilled in the art that illustrated in theaccompanying drawlng,

full protection is desired ,according to the scope i of the appendedclaims.

The invention claimed is:

.ing slot therein and a pair of Wall plates connected thereto.
